Abstract
In the present paper, the authors present the results of a GIS based analysis on the relationship between Sardinian nuraghi, megalithic dry stone buildings that represent the most common typology of monuments during the 2nd and the first centuries of the 1st millennium BC, and their landscape in terms of visibility. The adopted methodology focuses on the total viewshed concept, as a basic metric to assess visual properties. Four different Sardinian sub regions (Sinis, Siniscola, Marmilla, and Dorgali) and their nuraghi have been considered into the analysis, representing a significant – albeit partial – sample of the variability in locational choices found across the island. Results highlight a widespread interest in visibility from and to nuraghi, with the exception of the Sinis Peninsula, where nuraghi do not seem to act as landmarks. Moreover, no significant differences in visibility have been found between simple and complex nuraghi, while visibility data for nuraccheddus (generally considered to be unfinished nuraghi towers) seems to be compatible with a marginal landscape-level role.
